Q

What does drugs acting on GI Secretions do?

A

Decrease GI secretory activity

Block the action of GI secretions

Form protective coverings on the GI lining to prevent erosion from GI secretions

Replace missing GI enzymes that the GI tract or ancillary glands and organs can no longer produce

Every drug works differently!

Q

What are the cause of Peptic Ulcer Disease?

A
  • NSAID use for example ibuprofen. This is because NSAIDS reduce prostaglandin secretion and prostaglandin protect the gastric mucosae. Without this protection the stomach cannot protect the mucosa from gastric acid.
  • Bacterial infection by Helicobacter pylori bacteria
  • Stress: physical and psychological

Q

What are important things to remember when giving drugs that affect GI secretions in children?

A

Children may use antacids, H2 Antagonist’s & PPI’s (protein pump inhibitors)

Concerns for this age group would be electrolyte imbalances and interference with nutrition (from side effects).

Q

What are important things to remember when giving drugs that affect GI secretions in adults?

A

Some concerns would be:
* Overuse (OTC)
* GI discomfort continuing (Continued OTC use without following up with provider to assess for underlying causes)
* Electrolyte disturbance
* Interference with other drugs

There are many issues that may arise from long-term use - over a year can result to C-diff & bone loss.

The drugs have not been cleared safe for pregnancy/lactation and may enter into breastmilk

  • Misoprostol - will result in miscarriage (cat.x) - Abortifacient

Q

What are important things to remember when giving drugs that affect GI secretions in older adults?

A

There may be long term effects when these drug are prescribed frequently

We should prescribe these with caution for patients with renal/hepatic impairments - slower metabolism and excretion.

Many OTC drugs contain the same agents and may also interfere with RX medication (ensure accidental OD does not occur)

We may see adverse reactions such as rebound acidity - which happens when stomach becomes alkaline from taking antacid so it produces more acid.

Alkalosis - from neutralizing effect.
Constipation or Diarrhea

Calcium Bicarbonate in particular may cause Hypercalcemia and Hypophosphatemia - because calcium and phosphate have an inverse relationship.

Patient teaching

52
Q

If the patient is prescribed NSAIDs as a treatment, should they take Misoprostol at the same time as they’re taking the NSAIDs?

Monitor nutritional status.

*Monitor for electrolyte imbalances with saliva substitutes due to underlying conditions that could be exacerbated by electrolyte imbalances.

*Patient teaching

64
Q

A

Protects stomach by inhibiting gastric acid secretion.

Increasing bicarbonate and mucous production in the stomach.

65
Q

Explain why NSAIDs are most common cause of Peptic Ulcer disease.

A

NSAIDs reduce prostaglandin secretions and prostaglandins protect the lining of the gastric mucosae. Without the prostaglandin protection, the stomach cannot protect itself form the gastric acids.

66
Q

What is the worry when it comes to long terms use of the GI secretion agents? what may happen?

A

long-term use - over a year can result to C-diff, electrolyte imbalances & bone loss

67

A

Misoprostol.

68
Q

What is Zollinger–Ellison syndrome, and which drug(s) may we use to treat this disease?

A

A disease where the stomach is producing excess amounts of secretions. We may use H2 Antagonists such as Cimetidine to treat this and also Proton Pump Inhibitors such as Lansoprazole.

69
Q

Which drug category reduces the amount of HCL secretion into the stomach?

A

Histamine 2 Antagonists : Cimetidine, Famotidine and Nizatidine and PPI’s Omeprazole, Lansoprazole.

70
Q

Are there H2 receptors on the heart?

A

Yes. This is why we have to be cautious with patients who have heart conditions when prescribing Histamine - 2 receptors as it may lead or exacerbate cardiac arrythmias and hypotension.

71
Q

With what type of administration are we more likely to see the adverse effect of cardiac arrythmias in patients who are taking Nizatidine?

A

Nizatidine is a H2 antagonist and we are most likely to see cardiac arrythmias when these drugs are administered via IV. Patients should therefore be monitored closely when given medications this way.

72
Q

Which drug category end in “tidine”

A

H2 antagonists

73
Q

Which drug category neutralizes stomach acid by a direct chemical reaction? Names some drug classes in this category.

A

Antacids
Sodium bicarbonate & Magnesium salts

74
Q

Explain rebound acidity

A

When the stomach becomes alkaline from taking antacid so it produces more acid, or may occur when your stomach produces extra acid after you’ve stopped taking an acid-suppressing medication like a PPI or H2 blocker. This may lead to an dependency on the drugs.

75
Q

What inverse relationship causes a drop in phosphate (hypophosphatemia)?

A

A spike in Calcium - Hypercalcemia.
If there is an increase in calcium there will be a drop in phosphate. This may happen with use of the antacid Calcium Carbonate.

76
Q

In relation to other drugs, when should Magnesium Salts be taken?

A

Magnesium Salts are Antacids and these should be taken 1 hr before or 2 hrs after other drugs because antacids may affect the absorption of the other drugs due to the altered chemical composition these drugs have of the stomach.

77
Q

Which drug blocks the secretion of HCL and which drug stops the production of HCL?

A

H2 antagonists ex. Cemetidine blocks the secretion of HCL by working on H2 receptor sites and partially blocks the production of Pepsin. Proton Pump Inhibitors such as Omeprazole by action on specific secretory surface receptors to precent the final step of HCL production.

78
Q

What drug class should Benzodiazepines & Phenytoin not be combined with, and why?

A

PPI’s such as Omeprazole due to risk of increased toxicity.

79
Q

Which drugs should not be given with anticogulants?

A

PPI’s due to some PPI’s increasing the effect of the coagulants and some PPIs decreasing the effect of the anticoagulants.

80
Q

Explain the action of Sucralfate

A

Forms an ulcer adherent at ulcer sites and protects the site from further damage from acid, pepsin, and bile salts.

81
Q

Which drug contains aluminum and may lead to build up of aluminum in patients with renal failure?

A

Sucralfate.
Sucralfate should also not be taken in conjunction with Aluminum salts due to this risk.

82
Q

When should Sucralfate be taken, and why is the timing important?

A

Sucralfate needs to be taken on an empty stomach to allow for the drug to adhere to the ulcer site. The drug should eb taken 1 hr. before or 2 hrs. after a meal and at bedtime.

83
Q

Which drug increases bicarb and mucous production in the stomach?

A

Misoprostol.

84
